    The purpose of this study was to analyse kinematic variable of alpine and freestyle snowboards" riding posture. A total of 6 elite male snowboard athletes(n=6; alpine:4, freestyle:2) were recruited to participate. The experiment was performed on a slope for intermediate(red-course) while the COG (Pelvis) acceleration data and lowlimb joint angles were recorded by IMU sensor(Noraxon, USA) and analysed. The participants were ridden through 12 gate poles with 12m gap. Results show that: In BSturn, the ROM of Righthip-flexion between alpine(37.78±15.08) and freeystyle(95.58±5.73) snowboards were significant difference(p<.05). In Fsturn, the ROM of Leftthip-flexion between alpine(38.67 ±6.63) and freeystyle(60.99±6.92) snowboards were significant difference(p<.05). The Leftthip-rotation"s ROM between alpine(75.15±7.59) and freeystyle(29.80±2.19) snowboards were significant difference (p<.05). Distinction between alpinesnowboard and freestyle snowboard posture is occurred by seeing ahead position in alpinesnowboard(like a ski). We need biomechanical understanding of characteristic between alpine and freestyle snowboards for top performance.
